Our Data Conversion Services

What
we Do:

Disc Interchange Service Company, DISC, specializes
in converting data stored on IBM Mainframe computers and on IBM AS/400 and iSeries midrange computers.
Data can be converted to other IBM computers or to ASCII computers like UNIX or Windows PCs.

DISC has converted billions
of records from tens of thousands of IBM mainframe tapes since we opened
in 1984. This has given us extensive experience with most tape, file,
and data types, and we know how to manipulate mainframe data to make it
usable on your PC or UNIX computer.

How
we Do it:

DISC is a custom shop -- we tailor each conversion to your
specifications, to meet your needs. We approach each job individually,
with the goal of solving your problems and producing the results you desire.
All conversions are done at our Westford, Mass. facilities by experienced data conversion programmers,
using an extensive network of conversion hardware and software we have developed over the last 32 years.

Data conversion is 100% of
our business, and we give it our full attention. We don't dilute
our focus on conversions by trying to do everything -- we concentrate on
doing one thing exceedingly well. We have invested heavily in supporting
most of the tape drives on the market, including the new IBM 3590B, 3590E,
and 3590H drives, IBM 3592, and StorageTek 9840 and 9940 drives.

One-Time Custom Conversions

Custom conversion from IBM Mainframe and AS/400 systems to PC or UNIX is our primary business. With tens-of-thousands of custom jobs successfully
completed in our 29 year history, we have the expertise, equipment, and know-how to
convert your files expertly.

DISC has extensive experience converting mainframe COBOL files to PCs. From the simplest mailing list to
the most complex financial data, we have the tools and knowledge to properly convert and Q.C. your files
efficiently and accurately.
We have the expertise to catch problems with the data before they cause you grief.

There is much more information about converting mainframe and AS/400 tape files to PC or UNIX files
on our IBM Mainframe and AS/400 Tape Conversions page,
and in our library of conversion articles, listed below.

Automated
Weekly Transaction Processing

DISC is very proficient at automating
conversions from mainframe tapes to PC files for daily, weekly, or monthly transaction
processing. DISC can read hundreds of different tape and file formats
and convert the data to the PC file type of your choice. In the conversion
process we can extract specific fields, perform record selection, and reformat
the data to your file specifications. If the file contains multiple
COBOL record types, we can split it into relational PC files. Of
course we perform all the common field conversions, and if you need the
data altered, such as converting Julian dates to Gregorian dates, we can
do that, too.

We build Quality-Control
checks into our programs, and it's standard procedure for us to generate
summary and Q.C. reports of the processing. The converted files can be
delivered via email, ftp, or on CD or floppy. And our service is
fast; we commonly process the data the day we receive the tapes.

Data Distribution

Let DISC handle your data distribution. Our fast and efficient service accepts all
your distribution data on a single tape and converts it to multiple files and formats
for distribution to many recipients. You just give us one database file and we handle the
rest. The data can be distributed in many file types, via disk, CD, email, or ftp.
